From the perspective of 2D game development, the main constraints are as follows:
2D art assets
2D rendering system
2D mapping
2D physics
Art asset constraints are mainly limited to graphical or visual assets, which include images, sprites, and fonts. It is not difficult to understand that a larger asset will take more time to process and render than a smaller asset, resulting in less performance quality.
It is not possible to deliver maximum display quality with a single set of assets in Android game development. This is the reason most Android game developers choose high-resolution assets as their base build. This normally performs well for high-configuration hardware platforms, but does not provide quality performance on low-configuration devices. Many developers opt for the option of porting for multiple resolution hardware platforms. This again takes time to complete the project.
